MACHINE FOR OPERATING CHURNS1 rSPECIIFICATIN forming part of LettersPatent No. 223,258, dated January 6, 1880.

Application led December 1, 1879.

To all whom it may concern Be it known that I, LEONARD G. SWEET, ofAmsterdam, in the county of Montgomery and State of New York, haveinvented certain new and useful Improvements in Machines for OperatingChnrns; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification.

Figure l is a perspective view. Fig. 2 is a vertical sectional viewtaken longitudinally through the crankshaft, and Fig. 3 is a verticalsectional view of Fig. 2.

Corresponding; parts in the several figures are denoted by like lettersof reference.

This invention relates to an improved machine for operating that classof churns which are provided with vertically reciprocatimgr dashers; and it consists in the construction and arrangement of the partsconstituting the same, which will be hereinafter fully described, andparticularly pointed out in the claim.

In the annexed drawings, A :represents a base provided with threeuprigl1ts,B B O, the two former of which are provided with brackets D D,extending in a direct-ion opposite to the upright O. The brackets D Dare connected by a cross-piece, E, supporting a fourth upright, F, thetop of which is connected with the upper ends of the remaining uprightsby a cross-brace, G.

The uprights B B are provided with boxes or bearings foracrank-shaft,-H, provided with balancewheels l l, disposed one on eachside of the crank. Upon the crank J of shaft H is adjusted a box, K,sliding in a horizontal slot, L, in a cross-head, M, adapted to slidevertically between the uprights C F, which are provided with suitableslots N, to receive the ends of said cross-head. The lower side of thecross-head M is provided with a stud, O, having an opening, P, toreceive the upper end of the dasher-staii.

Q is a bail, pivoted in the sides of the stud O so as to swing downwardand enter a notch, R, out in the side of the dasher-staff near its upperend, and thus attaching it securely to the cross-head.

The churn S is secured upon the base between the uprigh ts B B C bymeans of cleats T.

The crankshaft H may be operated by a hand-crank, U, or in any othersuitable manner.

The operation of my invention will be readily understood from theforegoing` description, taken in connection with the annexed drawings.It is simple,inexpensive, durable, and may be advantageously used tooperate any churns of the wellknown old-fashioned construction.

Having thus described myinvention, I claim and desire to secure byLetters Patent of the United States- As an improvement inchnrn-operating mechanisms, the frame A B B O D D E F Gr, Crankshaft H, havingslide-box K, and the crosshead M, having slot L, and recessed stud O,having pivoted bail Q, all constructed, arranged, and operating asdescribed,in combination with a dasherstai' having notch R, substantially as and for the purpose set forth.

ln testimony that I claim the foregoing as my own l have hereto affixedmy signature in presence of two witnesses.'
